  -----------
  Reapply "[Analyzer][CFG] Correctly handle rebuilt default arg and default init expression" (#127338)

This PR reapply https://github.com/llvm/llvm-project/pull/117437.
The issue has been fixed by the 2nd commit, we need to ignore parens in
CXXDefaultArgExpr when build CFG, because CXXDefaultArgExpr::getExpr
stripped off the top level FullExpr and ConstantExpr, ParenExpr may
occurres in the top level.
